The BlackBerry® Visor Mount Speakerphone VM-605 has a built-in FM transmitter that you can use to listen to audio files that are on your BlackBerry device or to listen to calls from your device through your vehicle's stereo system. You can only listen to either an audio file or a call at a time.
If you use the FM transmitter for a phone call, other people who use a radio near you might be able to hear your phone conversations.
In some countries, there might be restrictions on the use of FM transmitters. Always check the laws and regulations in the country in which you are using the BlackBerry Visor Mount Speakerphone VM-605.
The FM transmitter turns off automatically after 1 minute if you are not listening to an audio file or a call through your vehicle's stereo system.
